Hi there all, New here. Nice to meet you! So, I was recently given a pair of B&O Beovox (model 6427) speakers. As expected, one has foam rot on the woofer and the surrounds need replacing. I was thinking a rubber surround to avoid any future issues. Anyone know where I can source a suitable replacement? The procedure to change them doesn't look too complex, but i have never re-foamed a woofer. Any tips welcome. Would be fun to restore these. Secondly I need a 2 pin DIN cable adapter that goes to regular banana plugs, so I can connect to my modern Rotel amp. Anywhere I can get a set of these cheap? Found these but ouch, steep price!
It will not be the same woofer if you fit rubber surrounds instead of foam.If you compare the T/S parameters you can see that they are far off.I suggest you fit foam, where the producer fitted foam.

Hey Martin, this is good to know. In that case, are there any like for like foam replacement that you might recommend? Equally any good vendors for parts? I am UK based. I am hoping to do this on a tight budget.
Thanks. All very helpful! I will order some new foam surrounds there.
A further question on the speaker cables that terminate in the 2 pin DIN connectors. Can I simply cut these off, strip the wire back, twist together and add banana plug instead? Will this be okay from a wiring perspective? No ground issues, etc? Seems unlikely I'll ever be using an amp with DIN connectors.
Hey all. Just to report back, I spent this weekend completing the re-foam of these. Managed to remove the old foam no problem and clean up all the old glue, etc. I applied the new foam rings and centered the voice coil using a 50-90hz test tone. This was the step I was most nervous about, but it went fine and managed to get both centered with no buzzing or rattle. Re-assembled today and hooked them up.
First impression, they sound really nice. I am just working through a range of music, from folk to country, to metal, to drone, etc. They lack a bit of upper mid sparkle that my JBL LX Series have, but my ears have to adjust. My amp can only do, main speakers / or 'remote speakers', which has both pairs running (the BEO 6427 and the JBLs simultaneously). Running both pairs together is actually pretty nice.
Are there any other upgrades I can make to these BEO 6427speakers? I see some people upgrade / replace some caps in the crossover? Anyhow, THANK YOU to everyone for advice.
Gratifying to have done my first repair, feels great as these were destined for the tip.
Speaker pre-repair.
They are great speakers in their own right, and not as bad as some people seem to think, butkeep in mind that these were the smallest and cheapest speakers in the whole range.Comparing them to other quality brands could be a little unfair.
You can replace the capacitor (yes, capacitor, because there is just one in each cabinet), if you think the treble is a bit muddy.
Thanks Dillen, I have been running them for 2 days now, and now that my ears have adjusted, I actually quite like them. I'm not a hifi expert by any stretch of the imagination!
If I were to replace the capacitor, is there a go to replacement that most people see as an upgrade?
I actually also like them, particularly when I have nothing else (read: larger and more expensive) to compare with. They are really not THAT bad speakers.
Replacing the capacitors with a type that comes close to the sound of the original will bring back the original sound.Making them sound any better would be difficult - rest assured that B&O would have done it already.
Understood. So, it's worth replacing the old caps as they may have become a bit worn?
Without me having to totally disassemble them again to get cap values, can you recommend what I should buy as a suitable replacement?
